Adaptive Limited Feedback for Sum-Rate Maximizing Beamforming in Cooperative Multicell Systems
Adaptive Limited Feedback for Sum-Rate Maximizing Beamforming in Cooperative Multicell Systems
Base station cooperation improves the sum-rates that can be achieved in cellular systems. Conventional cooperation techniques require sharing large amounts of information over finite-capacity backhaul links and assume that base stations have full channel state information (CSI) of all the active users in the system. In this paper, a new …
